Morphology General Habit
Perennial; caespitose. Rhizomes short; pachymorph. Culms erect; 300 cm long; 20-30 mm diam.; woody. Culm-internodes terete; 8-20 cm long; distally glabrous. Lateral branches dendroid. Culm-sheaths 15-20 cm long; 2 times as long as wide; coriaceous; hispid; with dark brown hairs; truncate at apex. Culm-sheath ligule 3-5 mm high; lacerate. Culm-sheath blade lanceolate; 2-2.5 cm long. Ligule an eciliate membrane.
Morphology Reproductive morphology Inflorescences
Synflorescence bractiferous; clustered at the nodes; in globose clusters; 2-3 cm long; dense; 5-9 cm between clusters; with spathaceous subtending bracts; with axillary buds at base of spikelet; prophyllate below lateral spikelets; leafless between branches. Fertile spikelets sessile.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 3-4 fertile florets; without rhachilla extension. Spikelets oblong; laterally compressed; 8-15 mm long; 4.5-5 mm wide; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes suppressed between florets.
Fertile
Spikelets comprising 3-4 fertile florets; without rhachilla extension. Spikelets oblong; laterally compressed; 8-15 mm long; 4.5-5 mm wide; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes suppressed between florets.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes two; persistent; similar; shorter than spikelet. Lower glume ovate; 1-keeled. Lower glume primary vein ciliolate. Lower glume margins ciliolate. Lower glume apex acute. Upper glume ovate; chartaceous; 1-keeled. Upper glume primary vein ciliolate. Upper glume margins ciliolate. Upper glume apex acuminate.
Morphology Reproductive morphology Flowers Florets
Fertile lemma orbicular; 10 mm long; 8 mm wide; chartaceous; without keel. Lemma margins ciliate. Lemma apex acute. Palea 1 length of lemma; chartaceous; 2-keeled but the uppermost without keels. Palea keels ciliate. Palea apex entire, or dentate; 2 -fid.
Morphology Reproductive morphology Flowers
Lodicules absent. Anthers 6; 10 mm long; purple. Filaments united in a tube. Stigmas 1. Ovary pubescent on apex.
Morphology Reproductive morphology Fruits
Caryopsis with adherent pericarp.
